SPECEFICATION forming part of Letters Patent No. 307,309, dated October28, 1884.

Application filed May 3,1884. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES L. KIDDER, a citizen of the United States,residing at New Brunswick, in the county of Middlesex and State of NewJersey, have invented certain new and useful Improvements inSpring-Motors, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form part of thisspecification.

Figure 1 is a front view of the entire machine; Fig. 2, an end view ofthe left-hand'cnd of machine; Fig. 3, a top view of bearing-frame 1removed from the machine and supporting thewinding-cylinder,winding-shaft,bevel-wheels, and stop-work mechanism.Fig. 4 is an enlarged view of friction device used when winding by thefoot of the operator; Fig. 5, a sectional view of the same; Fig. 6, anenlarged view of center of wheel 0, with the frictionpawl, the hub inwhich the pawl is held, and the manner of fastening the same to theshaft. Fig. ,7 is an enlarged view of the mechanism by which I increaseor diminish the tension of the spring.

The legs or standards A A, with the table B, constitute the frame of themachine. the frame is fixed the bearing-frame shown in Fig. 3, uponwhich are supported the winding-shafts a and b. Through the frame belowthe bearingframe passes the shaft d. On the frame, as shown in Fig. 2,is hung the pendent lever G, with a foot-rest at its lower end andhaving attached to it two connection-bars, I and H.

The bar I, in connection with the pendent lever and the mechanism shownin Fig. 4, pro vides an easy and noiseless method of winding by the footof the operator or of renewing at intervals the power already expendedin running the machine, and the bar H, when connected with the crank 6,providing a simple means of running the machine by foot-power when byreason of breakage of the motor or for any other reason it is notdesired to use the motive power of the spring.

The motive power of the machine is a coilspring, D, contained within thefusee w, and 50 having oneend attached to the inside of the fusee, whilethe other is solidly connected with the shaft (Z. This shaft (1 is keptin position by the device shown in Fig. 7, by means of which, also, thetension of the spring can be increased or diminished, as may be desired.Upon the fusee or drum is wound a small cord, which is fastened at itsother end to the winding-cylinder E. Said cylinder E is actuated bymeans of its connection by frictionelutch u, (shown in Fig. 6,) toawinding-shaft adapted to be revolved by a crank fitted upon either end.The winding-cylinder can also be revolved by means of the foot windingapparatus shown in Fig. 3, and it is prevented from being wound tootightly by means of the safety 6 5 stop mechanism (shown in Fig. 8) rand p.

The principal features in this mechanism have already been patented tome. The novel features are the new method of winding by means of thefoot-lever G and the connected parts.

The operation of renewing the power by the use of my improvement is asfollows: The foot of the operator is placed upon the foot-rest g of thependent lever G, and the pendent lever 7 5 is swung toward him. Thismotion brings the spring h to bear upon the pin 17, which is made fastin the friction-pawl j, thus making a connection between it and theinside periphery of the wheel F, which is made fast to the shaft I). Thependent lever G is now swung away from the operator, thus turning thewheel F, the shaft 1), the bevel-wheels 7. and Z, the winding-cylinderE, and by means of the cord winding the spring contained in thespring-box D. 8 5 Upon stopping the pressure of the'foot against thependent lever G the small spring m (shown by dotted lines in Fig. 4)swings the frictionpawl forward and away from the inside periphery ofthe wheel F, leaving it free to turn 0 by the action of the drivingspring. It is to be particularly noticed in this connection that, unlikefriction-clutches now in use, my device turns the wheel F in onedirection and then instantly allows it to turn back again in the op- 9 5posite direction, whereas the common frictionclutch is adapted simply toturn a wheel continuously in one direction. This operation continuedgradually rewinds the spring.

The second improvement consists of the crank a on the end of thedriving-shaft 0, and the connection-bar H, attached to the pendent leverG, and adapted to connect the crank l l c with the pendent lever, andform a simple method of running the machine by foot-power, the springbeing entirely disconnected. The length of the bar H is such as toprevent the bar I from coming back so far as tolorm a connection betweenthe friction pawl j and the wheel F when the machine is being run byfoot-power.

Having thus set forth my in vent-ion, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In a spring-motor, friction-clutch having a lever impinging againstthe periphery of the wheel to be revolved and adapted to give such wheela forward movement when desired and to permitits backward movement assoon as the forward movement of the clutch and wheel have ceased,substantially as de scribed.

2. In a spring-motor, a shal't connecting the driving-wheel with themechanism operated by the 1notive-s )ring thereof so as to cause suchwheel to be driven thereby, and also adapt ed to communicate motion tothe driving-wheel from a power independent of the springpower of themechanism, substantially as described.

3. In a spring-motor, the combination, with the pendent lover, of awinding apparatus adapted to be operated by meansof a frictionclutch,substantially as set forth.

4. In a spring-motor, the combination of a l connecting-shal't having atone end a drivingwheel, devices constituting suitable means ofconnection to the motive power of the mechanism, a pendent lever, anddevices constituting suitable means 01 a connection between such leverand a shalt so arranged that motion may be imparted to the driving-wheelthrough such pendent lever inde iendcntly ol" the moti ve power ofthemechanism, all substantially as described.

v 5. Ina spring-motor, ihe combination of a fusee containing aspring-box, a spring eonnccted at one end to sncn box and secured at theother to a shalt, a winding cord or belt, a windirig-cylinder, afriction-clutch adapted to actuate the winding-cylinder, and devicesconstituting the means for connecting such clutch with a pendent lever,whereby the whole cornbination can be operated, subslaniiially as setforth.

(S. In a spring-ureter, a connecling-shaithaving at one end adrivingavhecl, and adapted at the other end to receive motion from avibrating pendent lever through proper devices constituting the means oiconnection, a gear wheel adapted to revolve rid connecting shal't, awimung-cylinder, windingshalt, a belt or cord, a 'l'usce or drumcontaining-a Spring-lam and spring connected thereto, all substantiallyas dcscri bed.
